To all whom it may concern: a

Be it known that l[, HARRY D. LATHROP, a citizen of the United States, and a resident of the city of Chicago, county ofCook and State of Illinois, have invented certain new and usefulllmprovements in Can-Inverting Means, of which the following is a specification.

My invention relates to new and useful improvements incan invertingmeans. and more particularly a can inverting mechanism used' in conjunction with a can washing machine, and has for its object thepros vision of a device of this class which is made up of few parts, which is economical to manufacture, an at the same time is ef- 'ficient and durable.

Other objects will appear hereinafter. This case is a division of my application filed November 24:, 1920, Serial No. t26,258. The invention consists inthe combinations andarrangements of parts hereinafter describedand claimed The invention will be best understood by reference to the accompanying drawingsforming a part of this specification, and in which,

Fig. 1 isa fragmentary side elevation of my invention. p Fig. 2 is a top plan view thereof, and

Fig. 3 is a vertical section taken on line I .3-3 of lFig. 2.

' This application is directed to the can invetting means used in conjunction with my improved can washing machine, which is fully disclosed in. the parent case, above identified. The frame 10 of the can washing machine is provided with a slideway 11 for the cans, which comprises a pair of angle irons 12 spaced apart in suitable position to support the cans 13 of the ordinary type the slideway'comprises a bar 17 which is stidable. longitudinally of the machine, and

is also adapted to be rocked. The slide bar 17 is provided with a plurality of spaced arms 18 for engaging the can successively and moving them. alongsald shdeway, n

ing the cans a step-by-stepsliding movement along the slideway l1, delivering a can at a time to the can lnverting means for turning the can from inverted t0 upright position, as is best shown in Fig. 3. The numerals 19 and 20 denote the trackway and receiving platform, respectively. of the cancover-delivery means, disclosed in my above identified case.

The means for turning the cans from their inverted position on the slideway into an upright position upon a platform 21 at the delivery end of the machine, and for holding them firmly in said u right position at this point forms the su ject matter of this invention. Said means comprises a rounded turning member in the form of a pair of superposed metal straps 22 which are secured at one end to the frame work 10, opposite the end of the slideway. As is best shown in Fig. 3,'the straps or bars 22 are curved downwardly away from the slideway, and then extend forwardly and upwardly, being turned downwardly again and secured at their lower ends to the frame work. By reason of the depression proand elevated portion of the bar 22'. T have found in practice that when a can is brought into engagement with my improved turning device in the course of a normal forwardmovement of the can under the in fluence of can forwarding' means, disclosed in the parent case above identified, the force of the forward movement of the can and the over-balanced weight} of the can in tipping serves to turn the can into upright position. Forreceiving the can 13 and for holding it against lateral tipping, thereby I ment of the upper cross bar 23. As is best completing the turning movement of the.

can, I have provided a cross bar 23 which is fixedly mounted at the upper ends of a pair of arms 24 pivotally mountedupon the frame work 10 by means of pivot pins 25. The lower end of the arms 2-1 are connected by a cross bar 26 which is of such a weight as to hold the upper cross bar 23 normally in position shown in Fig. 3. 'hen the can 13 is brought in contact with the cross bar 23, the cross bar is moved forwardly, as is shown in dotted lines in Fig. 3, serving to bring the lower cross bar 26 into contact with a stop 27 mounted upon the frame 10,

ing from the spirit of the invention. I

which stop serves to limit the forward moveshown in Fig. 2, the central portion ofthe cross bar 23 is curved forwardly, to conform substantially to the curvature of the side of the can, so as to hold the can from tipping laterally. By the time that a can is delivered in upright position upon the platform 21, as above described, two or three covers will be waiting on the adjacent platform 20 at the delivery end of the slideway 19 for covers. By this construction the can is properly inverted and is firmly held in upright position, at the delivery end of the can washing machine, permitting the cover, delivered on platform 20, to be immediately placed on .the can, thus enabling the cans and covers to bedelivered in a very expeditious manner.

While I have illustrated and described the preferred form of construction for carrying my invention into effect, this is'capable of variation and modification without depart- 7 therefore, do not wish to be limited to the precise details of the construction set forth, but desire to avail myself of such variations, and modifications as come within the scope of the appended claims.

Having described my invention, what I claim as new and desire to secure by Letters Patent, is

1. A can inverting means associated with the slideway of a can washing machine, said inverting means comprising ametallic strap projecting forwardly-from the center of theslideway, being bent upwardly and then downwardly adjacent the end of the slideway for permitting a can on the slideway to tip forwardly and to turn over said strap into upright position, an dmeans for engaging the lower portion of the can to complete the turning movement and to hold the can against tipping.

2. can inverting means associated with the slideway of a can washing machine, said invertlng means comprising a member mounted near the end of the slideway in slightly elevated position with respect thereto, adapted by engagement with the side of the can in its forward movement to give the near the end of the slideway, curved upward and then downward, adapted by engagement with the side of the can in its forward movement to give the can a turning movement; and a cross bar movably mounted opposite the end of the slideway adapted, by engagement with the can near its lower portion, to complete the turning movement of the can and to hold the can against tipping from assumed upright position.

4. A can inverting means associated with the slideway of a can washing machine, said inverting means comprising a curved member mounted near the end of the slideway in slightly elevated position with respect thereto, adapted by engagement with the side of of the can in its forward movement to give the can a turning movement and a cross bar curved to conform substantially to the shape ofthe can adapted by engagement with the can from said curved member to complete the turning movement and to hold the can against tipping laterally.

5. A can inverting means associated with the slideway of a can washing machine, said inverting means comprising a curved strap mounted at center of said slideway near the end thereof, adapted by engagement with the side of the-can in its forward movement to give the can a turning movement; arms pivotally mounted opposite the end of the slideway and movable toward and from the end of the slideway; a cross bar carried by said arms, adapted by engagement with the can near its lower portion to complete the turning movement of the can; and stop means for limiting the forward swing of said arms.

6. A can invertingQmeans associated with the slideway of a can washing machine, said inverting means comprising means near the end of the slideway in slightly elevated position with respect thereto, adapted by engagement with the side of the can in its forward movement to give.the 'can a turning to complete the turning movement of the can; means forholding said arms yieldingly in position; and stop means for limiting the forward swing of said arms.

7. A can invertin means rovided in a washing machine at the end 0 the slideway. said inverting means comprising a curved strap fastened to the machine frame at the end of the slideway and extending downposition; and stop means for limiting the ward, then upward and again downward, forward swing of said arms and bar.
